Description

We have studied the low-lying nucleon resonances N(1530), N(1440), and Lambda(1405) and the relevant interactions with Hamiltonian effective field theory. Combined with the meson-nucleon scattering data and the lattice QCD simulations, and even the S11 pion photoproduction data, we obtain different structures of these resonances. Furthermore, we investigate the kaonic hydrogen and deuteron with the same framework and notice the life of kaonic deuteron would become much short by considering the recoil effect of nucleon in deuteron, which may result from the existence of Lambda(1405) near threshold.
